*4.24 (Order three cities) Write a program that prompts the user to enter three cities and displays them in ascending order. Here is a sample run:

    Enter the first city: Chicago
    Enter the second city: Los Angeles
    Enter the third city: Atlanta
    The three cities in alphabetical order are Atlanta Chicago Los Angeles

import java.util.Scanner;
 
public class ProgrammingEx4_24 {
 
 public static void main(String[] args) {
  Scanner input = new Scanner(System.in);
  System.out.print("Enter the first city:");
  String first = input.nextLine();
  System.out.print("Enter the second city:");
  String second = input.nextLine();
  System.out.print("Enter the third city:");
  String third = input.nextLine();
  String temp = "";
 
  if (first.compareTo(second) > 0) {
   temp = second;
   second = first;
   first = temp;
 
  }
  if (second.compareTo(third) > 0) {
   temp = third;
   third = second;
   second = temp;
 
  }
  if (first.compareTo(second) > 0) {
   temp = second;
   second = first;
   first = temp;
 
  }
  System.out.println("The three cities in alphabetical order are "
    + first + " " + second + " " + third);
 }
